"Nightmare Theater" was a hosted horror movie show on WTTV-4 Bloomington Indiana, with horror host Sammy Terry played by Bob Carter. It began 7 September 1963 and ended 2 April 1976.

WTTV Channel 4 Bloomington Indiana had purchased the "Shock Theater" package from Universal Studios and had originally aired it as "Shock Theater" and only included still photographs punctuated by voice-over narrations by Bob during the commercial break. A sponsor told the station that they wanted the voice of Bob Carter to host the new Nightmare Theater. Bob invented the horror host Sammy Terry and the rest is history.—The Professor
